if it has a 3.3 there is no map sensor
The 2000 Mazda ProtÃ©gÃ© map sensor is located next to the system computer. The map sensor and the system computer can be found behind the kick plate on the passenger side of the passenger compartment.
The map sensor on a 1990 Ford 5.8 EFI Bronco is on the passenger side. It is located on the firewall.
The PCV valve is located under the MAP sensor on a 1990 Pontiac Grand Prix. The MAP sensor is in the upper plenum.
On the firewall on the pass side.
After consulting several sources, someone finally called a local Buick dealer who informed me that a 1990 LeSabre does NOT have a map sensor, it was the Mass Air Flow sensor that needs replacing.
The map sensor is located on the fire wall towards the passenger side right under the wind shield.
